A Uefa statement said: "Uefa has opened disciplinary proceedings against Manchester United FC for [the] red card of Nani [and] post-match media obligations not fulfilled [under] III 2.6 and 2.7 of the competition regulations. The case will be dealt with by the Uefa control and disciplinary body on Thursday 21 March."

Ferguson was left "distraught" by the decision to send off Nani and was not "in any fit state to talk", according to his assistant, Mike Phelan. Uefa rules state all managers must attend post-match press conferences. While Ferguson speaks to television after domestic league and cup games, the Scot refuses to be present at briefings with the print media.
